ceph: cleanup return error of try_get_cap_refs()
Returns 0 if caps were not able to be acquired (yet), 1 if cap
acquisition succeeded, or a negative error code. There are 3 special
error codes:
-EAGAIN: need to sleep but non-blocking is specified
-EFBIG: ask caller to call check_max_size() and try again.
-ESTALE: ask caller to call ceph_renew_caps() and try again.
[ jlayton: add WARN_ON_ONCE check for -EAGAIN ]
